SMOKING PIPE.

Application` filed September 21, 1922. Serial No. 589,641.

To all whom t may concern: l

Be it known that I, JOHN H. SGHRODER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Smoking Pipes, of which the following is a specification.

This invention relates to tobacco pipes and the main object is to provide a pipe in which, the smoke may be cooled without the use of a long stem, and in which the pipe may be easily 'cleaned Further objects will be disclosed in the course of the following specification and are clearly illustrated in the accompanying drawing, wherein:

Fig. 1 is an elevation of the pipe, the greater portion of which is shown in longitudinal vertical section.

Fig. 2 is a detail section on the line 2-2 in Fig. 1.

Fig. 3 is a detail view of the spirally grooved cooling piece 19.

Referring to the drawing more particularly and by reference characters, 4 designates the tobacco` bowl of a pipe having a stem 5 and a mouth piece 6. The bowl 4 is provided at its lower end with a cylindrical opening 7 in which is rictionally secured a disk 8. A button 9 is loosely slidable in lthe opening 7 and is provided with a pin 10 which is slidably retained in the disk 8. A

spring 11 is interposed between the disk-8 and I the button 9 and yieldingly holds the latter and the pin 10 'in a downward position, as shown. When the butto-n 9 is pushed in with the Vlinger the pin 10 moves up into a hole 12, through which the smoke from the bowl is normally drawn.

The stem 5, which is preferably riction ally retained in the bowl, has an aperture 13 at the upper part of its inner end, and at an intermediate point in its bottom is-provided with a cleaning port 14. The port 14 is normally closed by the projecting end 15 of a lever 16, which is pivoted as at 17 and has a spring 18 which yieldingly holds the projecting end of the lever in the port opening 14.

Within the stem 5 lis snugly fitted a cooling piece 19 which is spirally grooved so that the smoke, in passing from the aper- Thefpipe is smoked in the usual manner,

the smoke from the burning tobacco passing from the bowl through the passages 12 and 13, and on through the stem and` mouth piece to the smokers mouth.

It frequently happens, 1n any p1pe,that

the outlet of the bowl, such as 12, becomes clogged withV tobacco so that the smoke passage becomes blocked. When this occurs, in the present construction, it is only necessary to push the button 9 upward. This will poke the pin 10 lup into the hole 12 and clear it. When it is desired to `clean out the stem 5 and the piece19 therein, the button 9 is again pushed up. As it moves up it not only closes the hole 12 but also opens the port 14 by acting against the inner or short end of the lever 16. Now if the operator blows into the mouth piece 6 he willl blow much ofthe dirt and sediment-out through the port 14, as it is the only escape for the air. The pipe can of course beoccasionally taken apart for a better cleaning, it and when necessary.

It is understood that various modifica tions may be made in the invention, as above described, provided, however', that such modiications come within the spirit and scope ofthe appended claims.

Having now therefore fully shown and described my invention, what I claim to be new and desire to protect by Letters Patent 1. In a smoking pipe having a bowl and a stem secured at one end therein, said bowl having a smoke outlet and said stem having a normally closed cleaning port, a pin slidably arranged with one end near said out-let for engagement therein, a button on the `other end of the pin for actuating the same, and a lever' normally closing said port, said lever being actuable by said button.

2. A smoking pipe consisting of a bowl having a smoke outlet, a stem communicating therewith and having a cleaning port, a member normally closing the port, a pin adapted to slidably engage in and close the bowl outlet, means actuated by the pin to. i

operate the port clcfng member, and a spring for normally holding the pin in a retracted position.

3. A pipe Consisting; of a bowl having a stem provided With a @leaning port, said bowl having a smoke outlet and a eliamber in alignment tlierebelor, a disk arranged in the chamber, a pin sidably arranged in the disk for closing' engagement with the smoke outlet, and means arranged below 10 the disk for yieldingly holding the pin in retracted position with respect to the outlet- In itestimony whereof I afx my signa'- ture.- v

JOHN H. SCHRODER.
